1 Claim.

This invention relates to window controlling and operating devices and more particularly to power devices for actuating a series of windows in unison or individually.

An object of the invention is to provide means to raise and lower a plurality of window sash, such for instance as in cars and other public vehicles, mechanically without the expenditure of manual force.

l0 A further feature is in the provision of audible ing means.

Figure 3 is a similar sectional view taken on line 3-3 of Fig. 1. Figure 4 is an enlarged fragmentary longitudinal sectional View of the drive means.

Figure 5 is a vertical view taken on line 5-5 of Fig. 1, drawn to an enlarged scale.

Figure 6 is a similar view taken on line 6-6 of Fig. 1.

Figure 7 is another like sectional view taken on line 'l--'l of Fig. 1, further enlarged.

Figure 8 is a partial end view of the drive means.

Figure 9 is an enlarged side view of the operating means.

Figure 9a is an enlarged fragmentary view of the clutch elements in disengaged position.

Figure 9b is a similar view of the same elements in engaged position.

Figure 10 is a partial plan view looking on line Ill-I0 of Fig. 9.

Figure 11 is a fragmentary sectional view showing a modification of construction of the power applying means.

Figure 12 is a front View thereof. Figure 13 is a diagrammatic view of the signal circuit wiring.

Referring in greater detail to the drawings, the numeral l5 designates in general the outer wall of the structure, be it car, coach or stationary building, having an inner wall Hi, between which is a space !1.

Any number of windows, as l8, l9 and 20, pro- 135 vided with inner and outer slidable sash, respectively 2l 22, are mounted in the usual manner in the window frames (see Fig. 3) but it is to be noted that no counter-balancing weights, cords or the like are required.

Extending inwardly from the inner wall it, at one end of the structure, is a casing 23 in which is housed an electric motor 25, its shaft 26 being revolubly mounted horizontally in a plurality of bearings 27.

A series of sleeves 30, one for each window, are loosely confined on the shaft by anti-friction bearings 3| (see Fig. 4), these sleeves being threaded at their ends to produce worms 32 enmeshed with worm wheels 33 in threaded engage-- ment with upright screws 34, the upper ends of which are fixed in the inner sash frames 22.

One of the ends of each sleeve 30 has formed on it the teeth of a positive clutch 35, to engage the teeth 36 of a collar 3'! slidably keyed to a sleeve 38 fastened rigidly on the shaft 28.

A roll 39, fitting an annular groove of the collar 3'3, is carried by a saddle 38, upturned at its sides and front end, and connected, as at Hi), to one end of a curved compression spring 4! coiled around a curved reinforcement rod 32.

The outer end of the rod passes through a flanged guide bracket 3 having a pin 44 on which the inner end of a two armed lever is pivoted.

The shorter lever arm 45 is pivoted to the saddle 653, which receives the thrust of the spring ll; the longer arm 4? of the lever is disposed directly over the roll 39 and extended to operate as a handle in an emergency.

A lever 54 is provided with a downreaching angular beak 55 adapted to engage between the raised side portions of the saddle 40 resting thereon and normally contacting its closed end by gravity.

The opposite end of the lever 5 5 is pivotally connected at 5'! to the downreaching arm 58 of a three armed lever pivoted to the frame at 6!, its left hand arm 59 engaging a rod 65 provided at its upper end with an enlargement 6t passing slidably through the window sill to be contacted by the sash when lowered.

A spring 61 normally retains the levers in operative position.

The oppositely extending arm of the lever engages a rod 62 extending upwardly alongside the sash to a stop 53, being guided by a bar B l fixed rigidly to the upper part of the sash.

The lever 54 has an outturned flange H! at its upper edge, in register with the beak 55, and rotatably mounted in the flange is a stem 50 fixed in an actuating handle 53 by which it may be turned.

An angular detent H2 is rigid on the stem 50 to engage an angular groove H3 in a tubular casing 52 in which the stem is slidably and rotatably confined.

The stem 50 is drawn upwardly within the casing by an enclosed tension spring 52, attached at its upper end to a plug I M fixed in the casing, which is held to the frame by a pivot screw H5.

When the detent H2 is moved by the handle it into position to engage in the groove M3, the beak 55 is raised out of contact with the saddle 4U, permitting the handle 47 to be operated in engaging or disengaging the clutch 3535, thereby raising and lowering the sash, the clutch being normally disengaged by the effect of the spring l 9.

From the foregoing it will be clear that when the sash is moved downwardly to its lower limit, the lever arm 58 will be pushed to the left; also that when the sash is raised to its upper limit, the rod 62 is stressed, tilting the arm 58 in the same direction, and moving the lever 55 positively to the right, provided the handle '43 has positioned the detent H2 so as to be drawn into the groove H3, otherwise the detent and its associated parts prevent raising the beak from the saddle, which, together with the roll 39, are pressed to the left by the spring H, causing disengagement of the clutch elements 35-35.

A worm Tl], held by a set screw to the shaft 25, meshes with a worm gear H fixed on a spindle '62 (see Fig. 7), is provided with a clutch l3 slidable on the splined hub of the gear, to engage the hub id of an eccentric around which is a In the modification shown in Figs. 11 and 12 the sash 22 has an extending bar 85 threaded to engage a screw 86, fixed at its lower end in a bevel gear 8? meshed with a mating gear 88 secured on a short spindle 89 and provided with another bevel gear 98 meshed with a mating gear 9! on a shaft 92, driven in any convenient manner by the motor.

The electrical circuits, shown diagrammatically in Fig. 13, include the motor 25 having current conductors 96-97 in the latter of which is a switch 98.

A transformer I38 reduces current to conductors lillll2, in which circuit may be placed a bell B03, controlled by a switch I04, an incandescent bulb lElS, controlled by a switch H16, may also be placed in the circuit, thus providing both audible and visual signals that the window sashes are being operated.

From the foregoing it will be seen that each sash may be independently raised and lowered individually or simultaneously.

While certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangements, proportions, since and details thereof may be made without departing from the scope of the invention as defined in the appended claim.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent, is:-

A window sash operating mechanism comprising a motor having a horizontal shaft housed below the sash, a sleeve revoluble on the shaft and having worms formed in its ends, gears meshed with said worms, said gears having internal threads, screws engaged in the threads of said worm and fixed in the sash, and a clutch for manually coupling said sleeve to said shaft.
